Extraction of baicalin and characterization of its methylated derivatives. X-ray structure of 7-hydroxy-5,6-dimethoxyflavone 7-glucuronide methyl ester dihydrate

Extraction of baicalin and characterization of its methylated derivatives. X-ray structure of 7-hydroxy-5,6-dimethoxyflavone 7-glucuronide methyl ester dihydrate

Baicalin has been isolated and four of its methyl derivatives have been characterised by IR, UV, mass, 1 H and 13 C NMR and one of these, 7-hydroxy-5,6-dimethoxyflavone 7-glucuronide methyl ester, was subjected to an X-ray crystallographic analysis.
